　　自润滑复合材料能够在整个相对运动过程中在攻击反面形成转移膜。当与较硬的相对面滑动时，这些材料不可避免的磨损会产生磨屑。这些碎屑可能会从接触区逸出，或者可能（理想情况下）沉积在柜台表面上。

　　全部粘附的碎屑构成转移膜，它可能保护触点免受进一步磨损损坏。薄膜质量越高，保护率越高。

　　转印膜的质量通常与其特定的微观结构特征有关。成膜需要一致、均匀，转印膜需要有足够的覆盖率。

　　薄膜的另一个基本特性是它的坚固性。坚固性与薄膜承受持续摩擦应力作用的能力有关。我们还认为，转移膜的质量受到相关摩擦系统所决定的多种因素的影响。

　　转移膜也可以理解为对特定摩擦系统的响应，因此受到诱导的集体应力、相对表面的特定性能分布、自润滑材料的成分以及很可能的条件的影响。周围的气氛。

　　实际上，我们不开发转印膜。

　　我们设计的材料具有正确的特性组合，以增强它们形成坚固转移膜的能力，即使在非常苛刻的操作条件下也是如此。

　　作为材料设计师，更改材料始终是为材料赋予新功能的良好起点。

　　增强转移膜形成的潜在方法非常广泛，例如通过在复合材料中使用不同的体积分数来改变结构结构或改变材料的组成。

　　使用额外的填料是一种很有前途的改性方法，可以增强活性材料形成更好和更坚固的转移膜的能力。也可以使用不同填料的组合来产生协同效应并改善整体组成。

　　一种典型的滑动活性聚合物化合物是本研究的主题。该化合物由用 PTFE 颗粒改性的热塑性聚合物基质滑动组成。添加纳米颗粒以增强化合物的转移膜形成能力。

　　本研究中使用的种纳米填料是氧化物陶瓷性质，平均直径为 50 纳米。第二个粒子是平均直径约为25微米的碳同素异形体。这些颗粒的厚度为5-8纳米。

　　Self-lubricating composites are able to form transfer films on the attacking counter face throughout the relative motion. The unavoidable wear of these materials when sliding against the harder counter face generates wear debris. This debris can escape from the contact zone or may – ideally – deposit onto the counter surface.

　　The entirety of the permanently adhering debris constitutes the transfer film, which potentially protects the contact from further wear damage. A higher protection rate can be achieved when the film has high quality.

　　A transfer film’s quality is often linked to its specific microstructural features. The film formation needs to be consistent and uniform, and the transfer film needs to have a sufficient coverage rate.

　　The other essential property of the film is its robustness. Robustness is linked to the ability of the film to withstand ongoing tribological stress actions. We also believe that the quality of the transfer film is affected by diverse factors dictated by the related tribological system.

　　The transfer film can also be understood as a response to a specific tribological system and is thus impacted by the induced collective stress, the specific property profile of the opposing surface, the composition of the self-lubricating material, and most likely the conditions of the surrounding atmosphere.

　　How are transfer films designed and developed?

　　Actually, we don’t develop transfer films.

　　We design materials with the right combination of features to enhance their capabilities to form robust transfer films, even under very demanding operating conditions.

　　As a material designer, changing a well-known material is always a good starting point for imparting new features into a material.

　　The potential approaches for enhanced transfer film forming are very broad, such as changing the structural architecture or changing the material’s composition by using different volume fractions in the composite.

　　The use of additional fillers is a promising modification method for enhancing the capability of active materials to form better and more robust transfer films. It is also possible to use a combination of different fillers to create a synergy effect and improve the overall composition.

　　A typical slide-active polymer compound is the subject of this investigation. The compound consists of a thermoplastic polymer matrix slide-modified with PTFE particles. Nanoparticles are added to enhance the transfer film-forming capabilities of the compound.

　　The first nanofillers used in this study are of oxide ceramic nature with a mean diameter of 50 nanometers. The second particle was a carbon allotrope with a mean diameter of around 25 micrometers. The thickness of these particles is 5-8 nanometers.
